58. Dividing by a Half

Take the number 40, divide it by one-half, and then add 10. What result do you get?

Added 28 April 2020

Hint:

Dividing by a fraction is the same as multiplying by its reciprocal.

Solution:

Dividing 40 by one-half is equivalent to multiplying 40 by 2: 40 ÷ 0.5 = 40 × 2 = 80.
Add 10 to that result: 80 + 10 = 90.
Therefore, the correct answer is 90.
